In this activity, learners build a carousel toy that spins when pushed down.

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

This activity (on page 3 of the PDF under GPS: Baseball Activity) is a full inquiry investigation into how "bounciness" relates to the distance a ball will fly when hit off a batting tee.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this physics activity, learners conduct two experiments to explore free-falling.

In this activity, a spinning bicycle wheel resists efforts to tilt it and point the axle in a new direction.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

In this physics activity, learners attempt to lift a jar full of rice using only a spoon.

In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this quick activity (page 2 of PDF under GPS: Lava Flow Activity), learners will model how large depressions near the top of a volcano are formed by using an inflating and deflating balloon submerg

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.
